Project Gemini

Project Gemini was the second human spaceflight program in which the United States of America sent humans into space, between Projects Mercury and Apollo, during the years 1963-1966. Its objective was to develop techniques for advanced space travel, notably those necessary for Apollo, whose objective was to land men on the Moon. Gemini missions involved extravehicular activity and orbital maneuvers including rendezvous and docking.

Gemini Applications

The United States Air Force had an interest in the system, and decided to use their own modification of the spacecraft as the crew vehicle for the Manned Orbiting Laboratory. To this end, one of the unmanned Gemini spacecraft was refurbished and flown again atop a mockup of the MOL, sent into space by a Titan III-M. This was the first time a spacecraft went into space twice.

The USAF also had the notion of adapting the Gemini spacecraft for trying out military applications, such as crude observation of the ground (no specialized reconaissance camera could be carried) and practicing making rendezvous with suspicious satellites. This project was called Blue Gemini. The US Air Force did not like the fact that Gemini would have to be recovered by the US Navy, so they intended for Blue Gemini eventually to use the paraglider and land on three skids, something from the original design of Gemini.

At first some within NASA welcomed sharing of the cost with the USAF, but it was later agreed that NASA was better off operating Project Gemini by itself. MOL was cancelled in 1968 and Blue Gemini too was cancelled without any use by military astronauts.
